time warrior - find all tags associated with a tag, then find how much time was spent on each of those tags

twts.sh

#!/bin/bash
#time warrior tag summary
while IFS= read -r line;do
    tag="${line// -/ }"
    tag=`echo $tag`
    command="timew \""$1"\" \""$tag"\" summary :month"
    response=$(echo `timew \""$1"\" \""$tag"\" summary :month | tail -n 2 | head -n 1`)
    [[ $response = "No filtered data"* ]] && response="No data"
    printf "%-50s - %-30s\n" "$tag" "$response"
done < <(timew tags :month "$1" | tail -n +4 | head -n -1)

I tag tasks in task warrior with customer names, so I may have +customer +task1 +task2 +task3, etc.

I wanted to get the time spent on each task this month without getting getting the summary of each tag, so basically I want the output of:
twts customer
to give me a list of task1, task2, task3 and the time spent on each one.

So I made this bash script: I hope someone finds it useful.
